2-10.2 Coding and encoding

Encoding

When data is collected, to simplify, it will most probably need to be encoded. Encoding is tranfering the data into a form which computers understand; usually binary. 

Without encoding we would not be able to use computers effectively as most, if not all, can't quite remember every byte that makes every letter, number, pixel sound wave etc. 

Coding

data is usually coded before encoding to make the processing much fast and effective. Data is coded to to keep entrys short, saving space and time Eg M = male, F = female
